Former Celtic midfielder Vidar Riseth has urged the club to go after Rosenborg's Markus Henriksen.
The 19-year old Norway international has been heavily linked with the Hoops recently and Riseth suggests the Scottish champions should pay up to get the talented midfielder to Parkhead.
"He's only 19 but already he is too good for Norwegian football.
"Celtic would probably need to pay around £2.5m to get him but I believe that is a very good price - a bargain.
"In years to come he will be worth a lot more. Celtic could keep him for two or three seasons and then make a lot of money on him. Markus will get better as he gets older. He will play more international games and his value will increase.
"Celtic would be getting a first-team player who would improve their side immediately. But he could also make the club millions in the future.""Markus is the biggest talent in Norway right now and can become a star of the European game," he told SunSport.
